Any PC based system will allow for remote access (assuming of course that things are working well enough to do that.) Our users/installers do the same thing with CQC, and it's easily done. It does allow for a lot of flexibility to do things remotely.

Of course it's going to be a lot easier if the machine you are RDP'ing into isn't a media center machine that the customer has been surfing porn sites on since you installed it, and is loaded with viruses, but a machine locked away in the closet and never used directly, i.e. replacing the dedicated controller with a dedicated controller that can just do more things in one box.

That, to me, is where the benefits lie in PC based automation systems, and why we created a highly networked system, so that the back end can be kept away from the naughty bits.
